Suitability Analyses

Each suitability analysis has its own set of particular criteria that were used to develop the output. The links below explain these critera as well as provide a data sheet for field use when evaluating a site for mitigation. The analysis has a set of common criteria; shared geoprocesses were used, as appropriate, based on the specific criteria outlined for each suitability analysis.

Upland Preservation
Map and score those areas where the natural upland ecosystem remains substantially intact and healthy.

Upland Restoration
Map and score those areas where the natural upland ecosystem remains substantially intact and healthy.

Wetland Preservation
Map and score those wetlands that are in great or pristine shape but which are not already permanently preserved via public conversation organization ownership, easement or deed restriction

Wetland Restoration
Find those areas that are not currently wetlands but which have site conditions that would support wetland creation. Restore the site to a healthy wetland.

Riparian Zone Preservation
Map and score areas near a stream but not in the stream that are contributing positively to stream health. Examples include area that are heavily wooded, or have other woody vegetation near the stream, which prevent erosion.

Riparian Zone Restoration
Map and score areas near a stream but not in the stream where the natural condition of the riparian zone has been compromised. Examples include areas where the stream quality is impaired, agricultural uses extend right up to the stream, woody vegetation has been removed, etc.

Preserve Natural Stormwater Infrastructure
Map and score those natural areas where current conditions support maximum groundwater recharge and/or minimal stormwater runoff. Permanently preserve those areas.

Restore Compromised Stormwater Infrastructure
Identify and score those areas where the natural hydrologic system is compromised and which are probably contributing to excessive runoff and inadequate recharge. These areas present opportunities to incorporate best management practices. Some factors indicate that problem are likely to exist, and some factors suggest an area is suitable for BMPs. Note, however, that the selection of a specific BMP needs to be made at the site level.

 

Shared Geoprocesses
A set of GIS processes relevant to two (2) or more of the suitability anaysis.
